I have a mapping like this:
{
"post": {
"properties": {
"author_gender": {
"type": "string",
"index": "not_analyzed",
"omit_norms": true,
"index_options": "docs"
},
"author_link": {
"type": "string",
"index": "no"
},
"content": {
"type": "string"
},
"mentions": {
"properties": {
"id": {
"type": "integer"
},
"name": {
"type": "string"
},
"profile_image_url": {
"type": "string"
},
"screen_name": {
"type": "string"
}
}
}
}
}
I need to search by the size of the mentions object. I have tried this:
{
"filter": {
"script": {
"script": "doc['mentions'].values.length == 2"
}
}
}
This is not working. Gives an error
nested: ElasticSearchIllegalArgumentException[No field found for [mentions] in mapping with types [post]];
I have also tried replacing the script part with doc['mentions.id'].value.length == 2. It is also erroring
nested: ArrayIndexOutOfBoundsException[10];
How to query records with mentions object size 2 ?

The size parameter is the maximum number of hits to return. Together, these two parameters define a page of results. Avoid using from and size to page too deeply or request too many results at once. Search requests usually span multiple shards.
Basically, a type in Elasticsearch represented a class of similar documents and had a name such as customer or item . Lucene has no concept of document data types, so Elasticsearch would store the type name of each document in a metadata field of a document called _type.
You can use the search API to search and aggregate data stored in Elasticsearch data streams or indices. The API's query request body parameter accepts queries written in Query DSL. The following request searches my-index-000001 using a match query. This query matches documents with a user.id value of kimchy .
The elasticsearch guide recommends using size() instead of length for objects. So try this:
{
"filter": {
"script": {
"script": "doc['mentions.id'].values.size() == 2"
}
}
}
All the best.
